From: Fredrik Tolf Date: Sat, 21 Sep 2013 20:47:10 +0000 (+0200) Subject: Make perf attributes depending on the resource module optional. X-Git-Tag: 0.2^0 X-Git-Url: http://git.dolda2000.com/gitweb/?a=commitdiff_plain;h=796cc8b9eaf6c0024ecd0c0d2e13e92416df1c22;hp=0eaf2431e1ea4e5aabb599d381bff7e71ae69fe9;p=pdm.git Make perf attributes depending on the resource module optional. This makes the module usable on Python implementations, such as Jython, that lack the resource module. --- diff --git a/pdm/perf.py b/pdm/perf.py index f3a3e70..8326884 100644 --- a/pdm/perf.py +++ b/pdm/perf.py @@ -45,7 +45,7 @@ It contains two named PERF objects: - platform -- An attribute returning the Python build platform.
